Can. i wonder on the ground there, what are people saying about their belief in vladimir putin s desire to negotiate? reporter: katy, we re not hearing a lot of optimism about the u.n. sec general s trip to moscow. he s appealed to vladimir putin several times at distance for a cease-fire, ignored every time. he s going to try again today, face-to-face inside the kremlin. we ll see if he has anymore luck. i ll tell you expectations are not high here. the working assumptions among ukrainians both in government and people on the street is that vladimir putin has absolutely no desire to negotiate with any seriousness. we are hearing some frustration here in ukraine that the secretary-general of the united nations decided to go to moscow first and then head to kyiv tomorrow to meet with president zelenskyy. a lot of ukrainians say this trip should have gone the other way around, the secretary-general should have walked the streets of bucha.
